Background bro 

A bro that is always at a party but never seems to get in on drinking games or other party activities. He can be seen casually sipping at his beer whilst chilling from a distance or adding the occasional chuckle and/or witty comment. They are very rarely seen alone, usually in groups of 2 or 3 so as to seem like they are having fun. Can also be abbreviated to BGB.

Yeah guys I'm out this time, I'll just background bro it.

Yo get in on this kegstand, don't be such a background bro!

bro PhD 

A person who uses broscience often to try to prove points or explain things. Usually the broscience comes directly from his mind with no outside sources and no experience with the topic he is talking about.

Bro PhD Kyle just tried to explain the creation of the HIV virus, of course talking straight broscience the whole time. I didn't believe a word he said.

deja bro

The experience of inexplicable familiarity felt when seeing a bro in a social setting (e.g. a party). This familiarity is often inexplicable due to excessive consumption of alcohol by both parties. But following a conversation between the two bros and some hard thinking, it is usually surmised that they met in class, saw each other on campus, or ran into each other in some other random setting. This often leads to good-natured conversation about their limited commonality over drinks.

Bro #1: "Bro, I've got total deja bro right now? Where have I seen you before?"

Bro #2: "Yeah same, dawg. Did we have a finance class together or something?"

Bro #1: "Yeah! Now I remember, I was mad hungover when you did some dumb ass presentation or something!"

Bro #2: "Tight, bro! That makes two of us!"

(they high five, cheers their cans of Natty Ice, and chug)
